Abstract

Perkembangan teknologi informasi mendorong pemanfaatan data secara lebih optimal dalam berbagai sektor pelayanan publik, termasuk di lingkungan Kepolisian Republik Indonesia. Sentra Pelayanan Kepolisian Terpadu (SPKT) Polres Asahan memiliki peran strategis sebagai unit pelayanan pertama dalam menerima laporan masyarakat terkait tindak kriminal. Namun, data laporan yang tersedia selama ini masih sebatas arsip administratif dan belum dimanfaatkan secara maksimal untuk analisis prediktif. Penelitian ini bertujuan untuk menerapkan metode regresi linear dalam memprediksi tren jumlah laporan masyarakat di SPKT Polres Asahan berdasarkan data historis yang tersedia. Metode penelitian yang digunakan adalah kuantitatif deskriptif dengan pendekatan data mining. Data diperoleh melalui wawancara, observasi, dokumentasi, dan studi pustaka, kemudian dianalisis menggunakan regresi linear untuk mengetahui hubungan antara variabel waktu dan jumlah laporan masyarakat. Hasil penelitian diperoleh nilai prediksi (Y’) sebesar 42.170455 yang menunjukkan bahwa tingkat risiko atau tingkat kejahatan  pada SPKT Polres Asahan pada periode Januari 2026 yaitu 42.170455. Nilai RMSE 0,421936 dan nilai koefisien jorelasi determinasi sebesar  r2=1.666666667 yang mengindikasikan tingkat kesalahan prediksi yang relatif rendah, sehingga model dinilai cukup akurat dalam merepresentasikan pola tren laporan. Hasil ini menggambarkan pola dan tren laporan masyarakat secara terukur serta menghasilkan prediksi yang dapat digunakan sebagai dasar perencanaan dan pengambilan keputusan.

Abstract

Rice farming plays a strategic role in Indonesia's economy and food security because rice is the main source of energy for the community. Rice yields are greatly influenced by environmental factors, particularly weather and soil conditions. This study aims to predict rice yields by utilizing machine learning technology using multiple linear regression methods. The research was conducted in West Ungaran District with independent variables in the form of weather and soil condition data and dependent variables in the form of rice harvest yields. The analysis results show that the multiple linear regression model is valid and significant, as proven by the ANOVA test with a significance value of 0.03 (< 0.05). The correlation coefficient value of 0.739 indicates a strong relationship, while the coefficient of determination (R square) value of 0.630 indicates that 63% of the variation in yield can be explained by the model. These findings show that machine learning has the potential to support decision-making in maintaining food production stability.

Abstract

Tourism village development is an important strategy for improving the economy and welfare of rural communities through professional, effective, and sustainable tourism destination management. Sustainable tourism is expected to reduce poverty, minimize social inequality, strengthen village development funding, and maintain public order. However, the success of tourism village development greatly depends on the synergy of village institutions, particularly in the implementation of Village-Owned Enterprise (BUMDes) policies, both in terms of strengthening product icons and digital marketing. This study uses a qualitative approach. Primary data were obtained through interviews with BUMDes managers, MSME actors, tourism village managers, and the Village Community Empowerment Agency (BPMD) in Garut Regency, while secondary data were sourced from literature, journals, and relevant websites. The research population included tourism villages and legally registered BUMDes in Garut Regency, with a sample consisting of six tourism villages, 30 respondents, and four informants selected using purposive sampling. Data validity was tested using triangulation techniques. The results show that tourism village development through digital marketing, product icons, and tourism village incubation approaches achieved varying outcomes. The implementation of digital marketing and product icon development remains suboptimal, as indicated by the limited use of digital platforms and the lack of competitive flagship products. In contrast, the tourism village incubation aspect is relatively better, reflected in the fairly well-organized BUMDes organizational structure and relatively active community involvement, although it has not yet been formally accumulated. Therefore, collaboration among stakeholders needs to be strengthened in order to realize sustainable and competitive tourism villages.

Abstract

Selecting high-quality coffee beans is a critical factor in maintaining flavor consistency in the coffee beverage industry. At Kopi Luar Dalam, the raw material selection process is still conducted subjectively, which can lead to inconsistent decisions. This study aims to design and implement a Decision Support System using the Simple Additive Weighting (SAW) method to determine the best coffee beans based on four criteria: cost, aroma, bean color, and physical form. The study employs a quantitative approach involving decision matrix normalization and preference value calculation. The results show that the African Blue Mountain Arabica (A8) alternative obtained the highest preference value of 0.80 and is therefore recommended as the best raw material. Methodologically, this study demonstrates that the application of SAW is capable of producing an objective, structured, and transparent selection process in the context of raw material selection for the SME-scale coffee industry.

Abstract

Determining objective employee rewards is a challenge for manufacturing companies because manual processes are prone to subjectivity and inconsistencies in evaluation. This study aims to develop a Decision Support System based on the integration of the Analytic Hierarchy Process (AHP) and MOORA to improve the accuracy and transparency of performance evaluations. AHP is used to determine the weights of five criteria through a consistency test (CR < 0.1), while MOORA is used for the ranking process of 69 employee alternatives. The results show that the system produces the best alternative with the highest preference value of 0.1474 and demonstrates ranking stability based on a weight sensitivity test (correlation coefficient 0.92). A comparison with the SAW and TOPSIS methods demonstrates the consistency of the best alternative; however, the AHP–MOORA approach provides more structured weight validation and better ranking stability. Scientifically, this study confirms the superiority of integrating weighting and optimization methods in producing a robust and verified decision-making model, particularly in the context of employee reward evaluation in the manufacturing sector.

Abstract

Choosing a college major is an important decision for high school students because it affects their future academic success and career. However, 12th-grade students at Kisaran Regional High School still struggle to determine a major that aligns with their interests and abilities. This study employs a quantitative approach using data mining methods via the K-Means Clustering algorithm to categorize students’ readiness levels in selecting a college major. Research data were obtained from questionnaires completed by 71 students based on five assessment aspects: interest in the major, alignment with academic performance, career information, environmental support, and personal maturity. The research instrument used a 1–5 Likert scale and was tested for reliability using Cronbach’s Alpha, which yielded a value of 0.87, indicating a good level of consistency. The research stages included data selection, transformation of qualitative data into numerical form, determination of the number of clusters (k=3), random initialization of the initial centroids, and calculation of distances using Euclidean Distance, performed iteratively until convergence was achieved. The results of the study indicate that out of 71 students, 23 students (32.39%) fall into the “very ready” category, 28 students (39.44%) into the “fairly ready” category, and 20 students (28.17%) into the “not yet ready” category regarding college major selection.

Abstract

This study aims to segment smartphone products based on the variables of Price, Rating, and Number of Reviews using the K-Means and K-Medoids methods. The dataset used consists of 400 smartphone products that have undergone data normalization as part of the preprocessing stage. The number of clusters was determined using an internal evaluation method, and the optimal number of clusters was found to be four (K=4). The clustering results show that both methods are capable of forming significantly different product group characteristics based on a combination of price level, user rating quality, and review intensity. The K-Means method produces a more structured cluster separation based on centroid values and is effective in representing the average data distribution. Meanwhile, K-Medoids demonstrate better resilience against outliers because cluster centers are represented by actual objects (medoids), making them more stable on heterogeneous data. Based on a comparative analysis of the methods’ characteristics and cluster evaluation results, K-Medoids demonstrates more robust performance for datasets with significant price variation. The findings of this study can serve as a basis for decision-making in marketing strategies and product clustering on e-commerce platforms.

Abstract

Public service is a key indicator in assessing the performance of government agencies, including the police. The Simpang Empat Police Station, as a technical police unit at the subdistrict level, plays a strategic role in providing services to the community. However, there are still complaints regarding long wait times, unfriendly officers, and suboptimal facilities. This study aims to evaluate the quality of public service at the Simpang Empat Police Station using the Simple Additive Weighting (SAW) method. The assessment was based on six criteria: service accuracy, officer attitude and behavior, service speed, clarity of information, transparency of the service process, and communication with the public. Data was collected through a questionnaire administered to service users. The results indicate that Mediation Services (A07) received the highest preference score of 0.9865, followed by Security and Order Services (A02) at 0.9792 and Guidance and Counseling Services (A05) at 0.9752. The average SAW score was 0.9706 with a satisfaction level of 97.06%, which falls into the “very satisfactory” category, indicating that the SAW method is effective for evaluating the quality of public services.

Abstract

Klasifikasi motif batik merupakan masalah pengenalan pola tekstur (fine-grained) yang dipengaruhi kualitas citra, fungsi kemiripan (similarity), dan strategi generalisasi model. Artikel ini menyajikan tinjauan sistematis berbasis PRISMA 2020 dengan fokus pada reduksi noise Gaussian, pendekatan kernel similarity, dan ensemble learning berbasis voting classifier. Sumber studi berasal dari tiga berkas bibliografi jejaring sitasi (Connected Papers) serta satu penambahan manual. Sebanyak 121 rekaman teridentifikasi; setelah penghapusan duplikasi (n=4) dan penyaringan judul-abstrak, 48 studi diikutkan dalam sintesis. Pemetaan menunjukkan dominasi metode CNN/deep learning dan fitur tekstur klasik (mis. GLCM) dengan pengklasifikasi KNN/SVM. Fokus kernel similarity muncul pada 7 studi, sedangkan ensemble/voting hanya pada 3 studi, reduksi noise Gaussian tidak muncul sebagai fokus eksplisit pada metadata (n=0). Temuan ini menegaskan gap pada evaluasi lintas-domain (daerah/kain/perangkat), benchmark robustness terhadap variasi pencahayaan/noise, penanganan ketidakseimbangan kelas, serta interpretabilitas model.
